Hi,
We investigated the logs in the regression failures that encountered
this and following are the findings:
1. snapshot clone failure is indeed the reason for the failure.
2. snapshot clone has failed in pre-validation with the error that the
brick of snap3 is not up and running.
3. snap3 was created, and subsequently started (because of
activate-on-create being enabled), long before we tried to create a
clone out of it.
4. The snap3's brick shows no failure logs, and thereby gives us no
reason to believe that it did not start properly in the course of the
testcase.
5. Which leaves us with the assumption (it is an assumption because we
do not have any logs backing it) that, there was some delay in either
the start of the brick process for snap3, or for glusterd to register
that the same has started, and before either of these events could have
happened the clone command got executed and failed. This would make
it a
race.
Some other things to consider about the particular testcase:
1. It did pass (and still passes consistently), in our local systems
making it not reproducible locally.
2. The patch was merged after both linux and netbsd regressions passed
(at one go).
3. The release 3.7 backported patch for the same, has also passed both
the linux and netbsd regressions as of now.
The rationale behind mentioning the above three points being, this
testcase has passed locally, as well as on the regression setups(not
just at the time of merge, but even now), which brings me back to the
assumption mentioned in point #5 . To get more clarity on the said
assumption we need access to one of the regression setups, so that we
can try reproducing the failure in that environment and get some proof
of what really is happening.
Vijay,
Could you please provide us with a jenkins linux slave to perform the
above mentioned validity
Please send out a request on gluster-infra if not done so and Michael
Scherer should be able to help.
Thanks!
Vijay
+ Adding gluster-infra and Michael

Thunderbird seems to be dropping to's in the mail. Added gluster-infra
